Three actuators are working as far as i can see. They all turn and the air seems to change except no heat.the actuator for the blend turns but all i get is cold air. Th ac stopped working this summer too. I dont think its a blocked heater core, as the system has been flushed regularly. There is a possibility the mice or squirrels moved in and broke the arm on the blend door or have the plenum box filled with junk. Anybody else have any ideas? Its cold, i need the truck, and i dont want to do work i dont have to. As a side note i am cheap as hell, and lazy to boot.
